Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a support for a car stop or the like that is conveniently attached to a parking lot or the like.

BACKGROUND OF THE INVENTION As shown in FIGS. 10 and 11, a stop body 41 41 pushed by a spring 40 is mounted on a presentation cylinder 4 using a conventional support such as a car stop.
It is known that the stop body 41.41 is engaged with a shallow annular groove 44 recessed above the sheath tube 43 when the presentation tube 42 is moved up and down as the presentation tube 42 is moved up and down. −
(See Publication No. 15192).

However, in this case, if the presentation cylinder 42 is pulled upward, the stop body 4
1 and 41 are locked in the annular shallow groove 44, and the presentation cylinder 42 is maintained in the raised state for the time being, but a slight external force such as a child's mischief causes the stop body 41, 41 and the annular shallow groove 44 to be locked in the locked state. There was a drawback that the presentation tube 42 would come off and the presentation tube 42 would descend.

Moreover, as shown in FIG. 12, when the main pillar 50 is raised,
There is a known device that locks into a locking piece 51 provided below and a locking hole 53 provided above the cover tube 52 (
(See Japanese Patent Publication No. 53-221).

However, in this case, the locking piece 51 and the locking hole 53 are locked and disengaged as the main pillar 50 rises and lowers by rotating while raising the pillar 50, or by rotating while lifting the pillar 50 somewhat. It is necessary to perform complicated operations such as lowering the
Furthermore, there is a drawback that if the locking hole 53 is damaged, the cover tube 52 must be replaced.

Technical Problem This invention is a solution to the above problem, and the technical problem is to obtain a support for a car stop or the like that is convenient to use.

Technical means To solve the above technical problem, this invention
An elevating column 2 is provided inside the elevating column 2 so as to be freely raised and lowered, and locking rods 4, 4 are provided at the lower part of the elevating column 2 to move in and out against a spring 3.
A locking portion 5 to which the locking rod 4.4 locks is provided at the top of the buried cylinder 1, and the locking portion 5 and the locking rods 4, 4 are disengaged as the lifting column 2 rotates. Buried cylinder 1 in the one formed in
A fitting tube 12 is provided on the top of the buried tube 1, which has an outer bent edge 9 at the upper end and an inner bent edge 11 with a central hole 10 at the lower end. The locking portion 5 has a fitting cylindrical member 14 placed on the inner bent edge 11, and the locking rods 4, 4 are attached below the fitting cylindrical member 14. A sliding inner hole 16 for the lifting column 2 is provided, and a locking step 17 on which the locking rods 4, 4 are placed is provided, and a locking step 17 is provided to protrude above the locking step 17. A rotation prevention step 22 , a guide step slope 18 connected to the rotation prevention step 22 , and a descending guide slope 19 whose upper end is connected to the guide step slope 18 and whose lower part is connected to the sliding inner hole 16 . A rotation blocking piece 20 protruding from the descending guide slope 19 is provided, and a stop plate 21 is placed on the upper surface of the fitting cylinder member 14. The pressing cylinder 23 presses a flange plate 25 provided with a guide insertion hole 24 of the lifting column 2, and the flange plate 25 is attached to a support such as a car stop that is detachably attached to the outer bent edge 9 via a second screw 26. This is related.

In addition, the locking rods 4, 4 attached to the lower part of the lifting column 2 are connected to the holes 6, 6.
The bulging portions 7, 7 are guided by a guide tube 8 as they move in and out.

Further, 23 is a pressing cylinder of the stop plate 21, and 27.2B,
29.30 is the 1st, 2nd. Third. 4th screw hole, 31.3
2 is a first and second notch, 33 is a cover plate, 34 is a drain hole,
35 is the underground part.

Effects and Effects This invention has the above-mentioned configuration, and when the lifting column 2 is raised, the locking rods 4, 4 are guided by the inclined surface 15 and pushed in, ascending the sliding inner hole 16, and the locking steps 17 Locking rod 4,
4 pops out and the elevating column 2 is held in the raised state.

To lower the lifting column 2, rotate the lifting column 2 and press the locking rod 4.
, 4 is the rotation prevention step 2 connected to the guide step slope 18.18.
2, the lifting column 2 is lifted and the locking rod 4.4 hits the stop plate 21, and when the lifting column 2 is further rotated, the locking rods 4, 4 are guided to the guide step slope 18.18. At the same time, it is guided by a descending guide slope 19, 19, and one of the locking rods 4 comes into contact with the rotation prevention piece 20.

If the lifting column 2 is then pushed down, the locking rods 4.4 are pushed into the holes 6, 6 against the spring 3, and the lifting column 2 can be pushed down.

Therefore, the lifting column 2 can be raised with an extremely simple operation, and the lifting column 2 can also be lowered easily as the lifting column 2 rotates, which is extremely suitable for use.

Further, the locking portion 5 that locks the locking rods 4, 4 has a fitting cylinder member 14 placed on the inwardly bent edge 11, and guides the locking rods 4, 4 below the fitting cylinder member 14. In addition, a sliding inner hole 16 for the lifting column 2 is provided, and a locking step 17 on which the locking rods 4, 4 are placed is provided, and a rotating portion protruding above the locking step 17 is provided. A guide step slope 18 connected to the blocking step 22 and the rotation preventing step 22, a descending guide slope 19 whose upper end is connected to the guide step slope 18 and whose lower part is connected to the sliding inner hole 16; Since the rotation prevention piece 20 protrudes from the guide slope 19 and is further formed with a stop plate 21 placed on the upper surface of the fitting cylinder member 14, the locking portion 5 may be damaged due to long-term use, and the locking rod 4, If the locking operation in step 4 cannot be carried out smoothly, the upper part of the buried cylinder 1 should be provided with an outwardly bent edge 9 located above the upper end of the buried cylinder 1, and a central part at the lower end. A fitting cylinder 12 provided with an inwardly bent edge 11 provided with a hole 10 is screwed with a first screw 13.
The stop plate 21 is removably fitted and attached via the cylinder 2.
3, and the pressing cylinder 23 was pressed by a flange plate 25 provided with a guide insertion hole 24 of the lifting column 2, and the flange plate 25 was removably attached to the outer bent edge 9 via a second screw 26. By loosening the second screw 13, taking out the fitting tube 12 from the buried tube 1, and replacing the fitting tube member 14, repairs can be made without digging out the buried tube 1, allowing smooth use at all times. Pillar 2
It is possible to easily and reliably raise and lower the lifting column 2 by simply raising the lifting column.
It is easy to operate because it can be held in a raised state without accidentally lowering it, and it can be lowered by simply rotating, lifting, and rotating.

Furthermore, it has a simple structure, is suitable for mass production, and can be provided at low cost, and has many practical effects.
